Red Tide map

Water samples this week show high levels of red tide near some Englewood and Boca Grande waters. Find the Florida Fish and Wildlife Conservation Commission's updated map at myfwc.com/research/redtide/.

ENGLEWOOD — Red tide is hanging around Englewood beaches and Lemon Bay, but maybe some relief is in sight: Signs show it’s clearing up to the north and south.

This week, though, crowds have been staying away from Manasota Key beaches for the most part.

Samples taken this week show high concentrations of the algae found at Englewood Beach and at the Boca Grande fishing pier on the northern part of Gasparilla Island. Those samples were collected Wednesday. A sample taken Monday at Gasparilla Pass near the Gasparilla Causeway showed low concentrations, according to the FWC.

Mote Marine Lab in Sarasota listed reports of some dead fish Friday at beaches at Boca Grande and Englewood, and at Caspersen Beach near Venice, but beaches to the north have mostly been clear of red tide in the water and dead fish.

Fish kills result when the toxic red tide algae, Karenia brevis, concentrations exceed 100,000 cells per liter of water. When cell concentrations reach a million or more, the algae can discolor the water, sometimes to a reddish brown.

Wildlife Conservation Commission, which regularly samples waters looking for the presence of the algae, reported low and very low concentrations around Boca Grande.

Red tide conditions can change daily. For more information about red tide and conditions, visit myfwc.com, the scgov.net Red Tide webpage, and visitbeaches.org.
